El objeto de la presente invención recae, concretamente, en el mecanismo de plegado de un carrito de bebé que concierne a las uniones articuladas de su estructura tubular entre las barras del manillar y las barras del bastidor de la sillita, y que son uno de los puntos esenciales que permiten doblar dicha estructura de una posición de uso a su posición de plegado, cuyo mecanismo, de manera innovadora, prevé la incorporación articulada de las fijaciones de los extremos de la barra quitamiedos de la sillita en dichas uniones para permitir el plegado conjunto de tal barra quitamiedos sin necesidad de extraerla para conseguir dicho plegado. The object of the present invention rests, specifically, in the folding mechanism of a baby carriage that concerns the articulated joints of its tubular structure between the handlebar bars and the saddle frame bars, and which are one of the essential points that allow said structure to be folded from a position of use to its folded position, whose mechanism, in an innovative way, provides for the articulated incorporation of the fasteners of the ends of the bar removed from the seat in said joints to allow the joint to fold of such a rod removed without the need to extract it to achieve said folding.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de carritos de bebé, centrándose particularmente en el ámbito de las estructuras plegables de los mismos. The field of application of the present invention falls within the sector of the industry dedicated to the manufacture of baby carriages, focusing particularly on the field of folding structures thereof.
HOJA DE REEMPLAZO (REGLA 26) ANTECEDENTES DE LA INVENCIÓN REPLACEMENT SHEET (RULE 26) BACKGROUND OF THE INVENTION
Actualmente, los carritos de bebé no se pueden plegar con la barra que se coloca por delante de los niños para evitar que salten del carrito, y que se conoce como barra de defensa, de seguridad o barra quitamiedos, cuando está dispuesta en su posición de uso, por lo que es necesario extraerla antes de plegar el carrito. Currently, the baby carriages cannot be folded with the bar that is placed in front of the children to prevent them from jumping out of the car, and which is known as a defense, safety bar or remover bar, when it is arranged in its position of use, so it is necessary to remove it before folding the cart.
Sin embargo, sacar dicha barra para plegar el carrito requiere bastante tiempo que, en muchos casos, no existe cuando el padre o la madre está con el niño. However, removing this bar to fold the cart requires a lot of time that, in many cases, does not exist when the father or mother is with the child.
Además, al sacar la barra del carrito y guardarla de manera independiente al mismo provoca, en muchas ocasiones, que la barra se pierda. In addition, removing the bar from the cart and storing it independently causes, in many cases, the bar to be lost.
Por ello, la barra quitamiedos, generalmente, se fija a la estructura del carrito mediante sendas uniones articuladas, expresamente previstas al efecto, que se acoplan en ambos lados del carrito, o bien a las barras de la parte superior que conforman el manillar o bien a las barras de la parte inferior que constituyen el bastidor de la sillita. Therefore, the rod remover, generally, is fixed to the structure of the cart by means of articulated joints, expressly provided for that purpose, which are attached on both sides of the cart, or to the bars of the upper part that make up the handlebar or to the bars at the bottom that constitute the seat frame.
El problema es que, al estar dicha barra quitamiedos fijada a dichas barras del manillar o del bastidor de la sillita, al plegar el carrito, se mueve juntamente con las barras a que está unida, hecho que impide que la estructura se cierre correctamente al chocar dicha barra quitamiedos y/o sus uniones con otras partes de la estructura del carrito, especialmente cuando el carrito presenta un mecanismo de plegado de la estructura con uniones articuladas entre los extremos inferiores de las barras del manillar y los extremos superiores de las barras del bastidor de la sillita, como es The problem is that, when said rod is attached to said bars of the handlebar or the seat frame, when folding the cart, it moves together with the bars to which it is attached, a fact that prevents the structure from closing properly when it hits said rod remover and / or its joints with other parts of the cart structure, especially when the cart has a folding mechanism of the structure with articulated joints between the lower ends of the handlebar bars and the upper ends of the frame bars of the seat, as is
HOJA DE REEMPLAZO (REGLA 26) el caso del mecanismo que aquí concierne. REPLACEMENT SHEET (RULE 26) the case of the mechanism that concerns here.
Concretamente, en cada una de las antedichas uniones articuladas de la estructura que permiten el plegado entre las barras que conforman el manillar y las barras que constituyen el bastidor de la sillita, actualmente, suele haber, al menos, dos piezas que, con una forma aproximada de disco, giran de manera concéntrica entre sí, la una que se une solidariamente al extremo inferior de la barra del manillar y la otra que se une de manera solidaria al extremo superior de la barra del bastidor de la sillita, normalmente la que queda en la parte anterior y finaliza en las ruedas delanteras, pudiendo opcionalmente incluir otra parte en forma de disco que también gira en la misma unión articulada y que está unida solidariamente al extremo superior de una segunda barra del bastidor de la sillita, en este caso la que termina inferiormente en las ruedas traseras; en cualquier caso, barras que, cuando se pliegan, acostumbran a situarse de manera casi paralela, mientras que en su posición de uso, con el carrito desplegado, dichas barras están dispuestas alineadas la una detrás de la otra la del manillar y la del bastidor que termina en las ruedas delanteras, y perpendicular a ellas la que termina en las ruedas traseras, existiendo, en los carritos individuales, dos de tales uniones articuladas, una a cada lado de la sillita, y en los carritos para gemelos o dobles, en los que la estructura comprende dos sillitas en paralelo con dos barras quitamiedos, tres uniones articuladas, una a cada lado y una en el centro entre ambas sillitas.  Specifically, in each of the aforementioned articulated joints of the structure that allow the folding between the bars that make up the handlebar and the bars that constitute the saddle frame, currently, there are usually at least two pieces that, with a shape approximate disc, rotate concentrically with each other, the one that joins the lower end of the handlebar jointly and the other that joins the upper end of the bar of the saddle frame, usually the one that remains in the front part and ends in the front wheels, being able to optionally include another disc-shaped part that also rotates in the same articulated joint and that is joined in solidarity with the upper end of a second bar of the seat frame, in this case the which ends inferiorly on the rear wheels; in any case, bars that, when folded, tend to be placed almost parallel, while in their position of use, with the cart unfolded, said bars are arranged aligned one behind the other, the handlebar and the frame which ends in the front wheels, and perpendicular to them the one that ends in the rear wheels, existing, in the individual carts, two such articulated joints, one on each side of the seat, and in the twin or double carts, in those that the structure comprises two chairs in parallel with two bars removed, three articulated joints, one on each side and one in the center between both chairs.
Pues bien, el objetivo de la presente invención es aprovechar dicho mecanismo con dicho tipo de uniones articuladas entre las barras de la parte superior y de la parte inferior de la estructura del carrito que determinan su plegarlo, para fijar la barra o barras quitamiedos y conseguir, principalmente, un mejor plegado del conjunto sin necesidad de desmontar dicha barra quitamiedos, pero además, eliminar un Well, the aim of the present invention is to take advantage of said mechanism with said type of articulated joints between the bars of the upper part and the lower part of the structure of the cart that determine its folding, to fix the bar or bars removed and achieve , mainly, a better folding of the assembly without the need to disassemble said rod remover, but also eliminate a
